EDWARD W. GRANT, OF YPSILANTI, MICHIGAN.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 244,888, dated July 26,1881.

,Application filed June 13, 1881.

To all whom it may concern Be it known that I, EDWARD W. GRANT, of

Ypsilanti, in the State of Michigan, have invented certain new anduseful Improvements in Gar-Couplings; and I do herebydeclare that thefollowin g is a full, clear, and exact description thereof, refencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form part of this specification, and in which- 4Figure l is a longitudinal section, showing the pin raised; Fig. 2,21similar view with the pin lowered; and Fig. 3 a detail, showing thedifierent parts of the coupling devices.

The primary object of this invention is to provide means for retainingthe coupling-pin in a raised position and automatically releasing it andallowing it to drop, by the action of the link against a weighted andpivoted catch; and to this end it consists in the combination, with adraw-head, of a pivoted bifurcatedlatch, a weighted and pivoted catch,and a couplingpin, all constructed and arranged to operate substantiallyin the manner hereinafter set forth and claimed.

In order that others skilled in the art may avail themselves of thebenefits of my invention, I will now particularly describe itsconstruction and operation. I

A represents the draw-head, which may beof the usual form, and providedon its upper side with ears or lugs to a and on its under side with earsor lugs a a.

Between the lugs a a, is pivoted the latch B. This latch is bifurcatedat its front end, and between its prongs is removably pivoted thecoupling-pin b. The rear end of the latch B is formed with a smallprojection, which. is

tween the lugs a a and a a, and is pivoted between the latter. The lowerend of this catch is curved or bent forward and weighted in order tothrow the upper end forward to engage or hold thelatch B when it isdesirable to have the pin in an elevated position. The pin being raisedthe upper hooked end of the catch 0 is thrown forward and engages withthe proi ecting end of the latch B,holdin g it in a raised position. If,now, it is desired to couple the cars, the link entering the draw-headstrikes the weighted catch, thus releasing the latch B and pin I) andallowing them to drop into place, automatically coupling the cars.

It will be observed that the head of catch 0 is beveled in order to restunder and against the projecting end of the latch B when the pin isdown, thus guarding against the link being released or the cars becominguncoupled by jolts or jars.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The combination, in a car-coupler, of a draw-head with a pivotedweighted catch, a pivoted latch for engagement therewith, and

the coupling-pin, all constructed and arranged to operate substantiallyas and for the purpose described.

2. The combination, in a car-coupler, of the pivoted latch B, having thecoupling-pin pivvoted to its front end and its rear end provided with aprojection, and the weighted catch 0, with its head adapted to restunder the projection on the latch when the pin is down, allsubstantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

EDWARD W. GRANT.
